IMPROVEMENT IN MACHINES FOR BENDING HOOKS.

Specification forming part of Letters Patent No. 131,289, datedSeptember 10, 1872.

To all whom it may concern:

Be it known that I, WESLEY MALIcK, 0 Erie, in the county of Erie andState of Pennsylvania, have invented a new and Improved Machine forMaking Hooks, and I do hereby declare the following to be a full, clear,and exact description of the same, reference being had to theaccompanying drawing and the letters of reference marked thereon, thesame forming a part of this specification.

The machine consists of three parts, namely: The forger or pointer, theeye-bender, and the snout-bender; and on these three parts of my machineare performed the three operations necessary to make a .hook, namely:drawing the ends of the blank, bending the eye, and bending the snout orright-angle bend of the hook.

My machine is shown in the accompanying drawing,-which consists ofSheets No. 1, No. 2, and N o. 3, as follows:

Figures 1 and 2 are respectively side and front views of the forging orpointing device.

3 and 4 are respectively vertical sectional and.

plan views of the eye-bending device, and Figs. 9,10, and 11 are viewsof the snoutbender, as follows: Fig. 9 is a horizontal sectional view,the dotted line as as seen in Figs. 10 and 11 being the line of section.Fig. 10 is a side view of one side, and Fig. 11 of the other side of thesnout-bending device; while on Sheet 3 the complete machine isillustrated Fig. 12 being a front view of the same, and Fig. 13 a planview, in which the distinctive features and their general arrangementare shown.

The following description will enable those skilled in the constructionof machinery to 'build and operate my devices: and first, of

that part of the machine on which the first operation is performed-via,the forger or point-drawing device. This is shown in Figs. 1 and 2, andconsists of a frame, K, in which are journaled oscillating gears L andL, which are operated by the shaft and crank H, pitman I, and lever J.On the opposite side of the frame from the operating devices just named,and hung on the shafts of the gears L and'L, are oscillating swages M"and M. These swages are of cast metal, and are quadrant-formed, theircircular faces meeting and pressing together, and in these are set maleand female dies N and 0, respectively. The position of these dies andtheir forms can be more fully seen in Fig. 2, where it will be seen thata circular space is formed between the dies. Both figures, 1 and 2, showthe swages M and M in a perpendicular position. Now the form of the diesis such that when the swages, by the operating machinery, are thrown outof the perpendicular the circular space between the dies is madesmaller. So, when the end of a blank is heated sufiiciently and insertedbetween the dies, when at the position shown in Fig. 2, and kept thereby the operator during one or more operations of the machine, the blankwill be drawn to a point, as shown in Fig. 5. This part of the machineis used to draw out both ends of the blank, and the form to which it isdrawn may be regulated by the operator after practice. And now comes thesecond operation-viz., bending the eye, and the device by which it isaccomplished. Figs. 3 and 4 illustrate that portion of my invention. Ofthis I? is the stand and Q is the top plate. R is the mandrel aroundwhich the eye is bent, and is stationed in the center of the top plateQ. It is movablethat is, it may be drawn out of the eye, when formed, bythe operator placing his foot on the lever V-the spring m again throwingit back in place when the pressure is removed from the lever. The blankis bent around the mandrel R by clamps T and S, which are op; erated bylevers U and W. The manner of bending the eye is as follows: Theoperator stands on the side of the device from which the lever V is seento protrude. He grasps a heated blank and shoves the pointed end inbetween the mandrel R and the clamp T until the end reaches the point con the clamp S. He then depresses the lever U; this throws the blank upagainst the flange j and partially around the mandrel R, bending theblank into the form shown in Fig. 7. He then grasps the lever W, andthis brings the clamp S to bear and this finishes the bending of theeye.

The lever V is depressed and the clamps T and S are thrown open and theblank appears. as shown in Fig. 6. Next comes the third part of mymachine-via, the snout-bender. This gives the right-angle crook to thehookcd part of the hook. Figs. 9, 10 and 11, on Sheet No. 2, show thispart of my device. All the parts of this device are attached to theframeplate G, and they consist of a plunger, B, clamp O, forming-head A,operating eccentric D, and propelling pinion F, and other minor parts.The operation of this part of my device is as follows! The blank q,shown by dotted lines in Fig. 9, is fed in in the position shown. Theoperator then depresses the lever c with his foot this brings to bearthe clamp G, holding the blank q tight against the face I) of theforming-head A. The point of the blank rests against the gage b of theplunger B. As soon as the blank is in position the eccentric D is readyto shove down the plunger B. The plunger is provided on its end with afriction-roller, a. As the plunger advances the friction-roller beginsto bear upon the 3. The pinion F, eccentric D, and plunger B incombination with the forming-head A.
